No matter what, I still believe in you. I admit I was a little.. well, fright. I wasn't sure how I'd fare against your other self. But now that you are yourself again, I still trust and accept you. Plus, you managed redemption fine to this point so I know you can succeed with it again.
As to Peter Pan, I assume you mean the one from your world, whom can't resist quoting "Pan never fails" every five minutes? And that cocky attitude, always wanted to reach in the TV and slap him I haven't seen him anywhere. But I'd notify everyone the moment I did.

I can't imagine anything that'd cause that. Aside from Pan, but so far none have spotted him. I suppose it might be possible for some magic of my world, but I'd never heard of it happening before, or even what purpose it would've served.
Could blame the Seal, but things like this it's usually best to find out if it's something or someone else.
